Many users do not like the new print user interface, so they have been staying with the old print user interface by setting print.tab_modal.enabled to false. Everything was fine until Firefox 97 removed this option. Many users have complained about this on support.mozilla.org.
I normally print to PDF and do not want a preview. I usually do a "postview" to check the resulting PDF. The new print user interface would just slow things down without providing me with any benefit. The old print preview should be available for those users who need it. I have reverted to Firefox 96.0.3.
Please bring back the whole of the old print user interface, i.e. what was provided by setting print.tab_modal.enabled to false.
